Power plants in Utah emitted 1421.2 lb CO2e per MWh generated in 2023 (0.6447 kg/kWh), 84% dirtier than the US average, according to EPA's eGRID2023 state rate. Their generation was 18% carbon-free and 18% renewable. For GHG Protocol Scope 2 location-based reporting, use the eGRID subregion factor of each facility's ZIP (below), not the state rate: power flows across state lines within a subregion.
All of Utah's ZIP codes are in the NWPP (WECC Northwest) eGRID subregion, whose Scope 2 factor is 635.267 lb CO2e/MWh (0.2882 kg/kWh).
Generation by power plants in Utah, 2023 (EPA eGRID2023 state resource mix).
Using the NWPP subregion factor (635.267 lb CO2e/MWh = 0.2882 kg/kWh). Source: EPA eGRID2023.
For GHG Protocol Scope 2 location-based emissions reporting, multiply each facility's electricity consumption by the emission factor for its ZIP code's eGRID subregion. All Utah ZIP codes use the NWPP factor: 635.267 lb CO2e/MWh.

For Scope 2 reporting, it depends on the ZIP: all are in NWPP, 635.267 lb CO2e/MWh. EPA's state rate for plants in Utah is 1421.2 lb CO2e/MWh, 84% dirtier than the US average.
Multiply the facility's annual kWh by the kg/kWh factor of its ZIP code's eGRID subregion (0.2882 for NWPP) to get kg CO2e, and divide by 1,000 for metric tonnes. The emission factors API returns the factor for any ZIP.
Power plants in Utah generated 18% carbon-free and 18% renewable electricity in 2023. At 1421 lb CO2e/MWh, the state rate is 84% dirtier than the US average of 770.9 lb/MWh.
